Discover Tile

Discover Tile is an app to test your observation and memory skills.
It will present a grid of tiles, then flash numbers on a subset of those.
Your task is to tap the correct tile in the numbered order.
Your first tap should be on the tile that showed 1, your second tap should be on the tile that showed 2, and so on.
For each correct tile and tap order, the tile will light up green with its number on it.
You have 3 minutes to get through as many levels as you can.
It starts fairly simple with a 3x3 tile grid, and 4 numbered tiles to remember, and moves on from there, increasing numbered tiles and the size of the tile grid.It is important to note that if you tap a tile out of order, you will have to continue for the next numbered tile.
I.e.
if you tap 1 correctly, but then tap the tile with 3 on your second tap, it will show red for wrong.
Your next tap have to be the same tile again as it will be your third tap.
This should turn that tile green indicating a correct tap.
